For machines like the xTool F2 Ultra , "wobble" settings act as a form of path compression, allowing the laser to move in a slight oscillating pattern to create wider, cleaner cuts. Material Thickness Recommended Spacing (Diameter × Ratio) Spacing Range 0.3–0.5 × Diameter 0.03–0.06 mm Medium Materials 0.3–0.5 × Diameter 0.06–0.09 mm Thick Materials 0.25–0.35 × Diameter 0.09–0.15 mm Source: xTool F2 Ultra Processing Parameters . 4. How to Find Your Custom "Sweet Spot"
Within the xTool software ecosystem (XCS), several settings interact with the precompression logic, most notably the "DPI" (Dots Per Inch) and "Passes." However, the specific precompressor adjustments often relate to how the image is interpreted and gray-scaled before the laser fires. xtool precompressor settings
Ranging from 1 to 1270 , a higher DPI results in a finer image but takes longer to process. For machines like the xTool F2 Ultra ,
| Problem | Likely Cause | Fix | | :--- | :--- | :--- | | Engraving looks | Precompressor too high | Reduce to 10-30% | | Burn marks between dots | Overlap compensation too low | Increase Precompressor to 60-80% | | Slow engraving with stuttering | Precompressor too low (raw data overload) | Increase to 40-60% | | White lines in dark fills | Overlap compensation too high (gaps) | Reduce Precompressor to 30-40% | How to Find Your Custom "Sweet Spot" Within
